Designing in PCF8561 lcd display driver.   Cannot get this question answered.


This IC calls for separate VLCD and VDD power supplies.    Our design will use a single 3.6V power supply for board so both pins will be powered from that supply.  Trying to figure out how to separate and handle the different pin supplies.   Ferrite beads?  Any other suggestion appreciated.   Thanks
